Generalized Noether symmetry in f(T) gravity

Understand

We consider modified teleparallel gravity, (f(T) gravity), as a framework to explain the present accelerated expansion of the universe.

• The matter component is assumed to be cold dark matter.
• To find the explicit form of the function $f$, we utilize generalized Noether theorem and use generalized vector fields as variational symmetries of the corresponding Lagrangian.
• We study the cosmological consequences of the obtained results.
